How to Convert a Floor Drain to a Shower Drain?- 6 steps Guide 

Installing a shower is very easy and it’ll save you a lot of money. Your floor drain will be useful again after the conversion. 

Both floor and shower drains have either p or s water traps. You don’t have to install one for your converted shower drain. This feature makes the plumbing process easier and quicker.

We’ve prepared a step-by-step guide to help you. Following this instruction will make the work easier.

Tools Needed

Before we go through the steps, collect the tools to complete the task. Here’s what you need-

  • Flat screwdriver
  • Compression wrench
  • Measuring tape
  • Angle grinders
  • Pipe cutter
  • Adhesive
  • Lubricant
  • Silicon sealant

Now that we have our tools, let’s start the process. Follow the steps carefully to successfully convert the floor drain.

Step 1 of 6: Prepare the Working Area

To begin with, turn off all the water supplies. Clean the floor before you start working on it. Make sure there is no dirt or debris near the shower drain. 

Dirt and other small particles can clog the drain. You can use a heavy cloth or towel to cover the drain to protect it during work.

Step 2 of 6: Cut the Tiles

To remove the floor drain, you have to cut the tiles around the area. Use an angle grinder to do this job.

In case you can’t find out, we have a list of excellent electric angle grinders for you-

Product 2

These are very sharp and cut tiles very fast. Use this angle grinder to cut your tile in any shape you like.

While cutting the tiles, keep the drain area covered with a cloth. Always be careful while working with angle grinders

Step 3 of 6: Remove the Floor Drain

Now that you’ve cut the tiles, you have to take out the floor drain. Take a flat screwdriver or knife to pop the strainer of the floor drain out. 

After taking out the strainer, you’ll see the compression nuts. Compression nuts keep the floor drain connected to the drainpipe. Remove the compression nuts and use a wrench to do this. Use your hand and take out the whole drain body.

Step 4 of 6: Install the Shower Drain Pipe

This is the most important part of the process. You have to cut the floor drain pipe and install the shower drain pipe. The pipe needs to be replaced because the shower drains are larger. They fit in 2’’ diameters. You need a 2’’ diameter pipe for installing your shower drain.

Use a measuring tape to determine how much you need to cut. Cut out the drain pipe using a pipe cutter. 

Now cut the shower drainpipe according to the floor drainpipe height.  Place the shower drain pipe and connect it to the main drain. Use strong lubricant for PVC pipes to connect the pipes. 

Step 5 of 6: Assemble the Shower Drain

A shower drain comes with separated parts. You have to assemble the parts before installing them,

Take the shower drain body and apply adhesive around the flange. Slide the rubber washer and slip-washer around the flange. 

Put the compression gasket and compression nut in the pipe. Now place the shower drain body on the pipe. Using a compression wrench, secure the connection. 

Step 6 of 6: Retile the Area

Now you need to retile the floor around the shower drain. Make sure you leave a ¼’’ slope during retiling. This will help the water to flow without any resistance to the drain.

First, apply a thin layer of mortar on the floor. Then put the tiles on the mortar. Use silicone sealant to fill up the gaps between the tiles. It is long-lasting and works better than grout sealant. 

And you’re done with converting the floor drain to a shower drain. That’s all you needed to know about the drain conversion. Now you can install your bathroom where the floor drain is.


Question: How much does a shower drain cost?

Answer: Shower drains cost around $50-60 with additional pipe fittings. Extra charges are added if you take help from a professional for installation.

Question: Can we convert the toilet drain to a shower drain?

Answer: The answer is simply no. It’ll cause you a huge problem as the toilet drainage pipe functions differently. If you try to do this, your shower will be flooded with drained water. This is not a good idea at all.

Question: What are the reasons for a clogged shower drain?

Answer: If the drain gets filled with dirt and solid obstacles, it can get clogged. A clogged drain is the main reason for water overflowing in the shower. Take professional help to remove the dirt from inside the pipe. That’ll unclog your shower drain.
